云南“本人”的红细胞血型分布及其与契丹人血缘关系的探讨

调查了云南省施甸县木老元乡哈寨村１０４名“本人”的４个细胞血型系统分布。结果表明,“本人”的ＡＢＯ血型系统分布特点是,基因频率ｐ（０．３０６９）〉基因频率ｑ（０．１７３９）;在ＭＮＳｓ血型系统中,基因频率ｍ（０．６５３８）〉基因频率ｎ（０．３４６２）;在Ｐ血型系统中,基因频率Ｐ１（０．１７９８）较低。这些均与我国南方少数民族的分布特点基本相符。与我国大部分地区一样。Ｒｈ因型系统的单倍型频率中最高的

THE DISTRIBUTION OF RED CELL BLOOD GROUPS IN "BEN REN" IN YUNNAN PROVINCE AND THEIR RELATIONSHIP WITH QIDAN

The distribution of 4 red cell blood group spstems was investigated on 104 "Ben Ren" students whose parents and grandparents are "Ben Ren" too, in Mulaoyuan Xiang, Shidian County, Yunnan Province. The results showed that in ABO system, the gene frequency p(0.3069) waslarger than the gene frequency q(0. 1739); in MNSs system, geng frequency m(0.6538) was largerthan the gene frequency n (0.3462); in P system, the gene frequency P1 wes low(0.1796). Allthese results tallied with the characteristics of southern ethnic groups in China. In the Rhsystem. like most populations in China, the CDe frequency(0.7980) of "Ben Ren"was largerthan that of oDE(0. 1322). Other gene frequencies were as follows: r=0.5192; MS=0.0288,Ms = 0.6250, Ns = 0.3462, S = 0.0288, s =0.9712, C =0.7981, c= 0.2019, D =0.9302, d=0.0698,E=0. 1321, e=0.8679, and the haplotype frequencies of NS. cDe. CDE. ode. Cde andCdE were all zero. The genetic distances and phylogenetic tree obtained on the basis of genefrequencies of 4 loci of "Ben Ren" and 17 populations show that the "Ben Ren" is genoticallydose to Vain, Achang, De'ang and other southern ethnic groups, but has long genetic distanceswith Northern ethnic groups and Han in Heilongjiang Province. However, there are eloquentevidences showing that the "Ben Ren" are offspring of Qidan, a Northern nomadic ethnic groupsome 1000 years ago. It can be concluded that the "Ben Ren" has mixed to a great extent withthe local ethnic minorities of Yunnan Province.
